Given the ease with which the average person can rattle off brand names like “Viagra” and “Cialis,” or joke about “four hour erections,” it would seem that erectile-dysfunction drugs are just about as common as ibuprofen.

We take it for granted, but the little blue pill has drastically changed the way we think about erectile disorder (ED).

Once known as “impotence,” ED was originally thought to be caused by anxiety, nerves, or low self-esteem; now it’s commonly known to be a health issue that hinges on the flow of blood to the penis and taking a pill to deal with the issue is often no big deal.

Don’t get me wrong: this is not to say that Viagra and its brethren – Levitra, Cialis and the new FDA-approved Stendra – are the be-all end-all, or even that they’re unequivocally effective.

The room was at full capacity - 200+ female triathletes of different abilities, all out there for the love of the sport. I can’t tell you when I've had a better audience.

Each member was racing or training for individual reasons, some finding more success than others, and some battling with their own adversity. At the same time they all had the same desire to push themselves to be better triathletes or even just healthier people.FULL POST
